Beyond the Triangle (ePub)

-->The book is devoted to the fundamental relationship between three objects: a stochastic process, stochastic differential equations driven by that process and their associated Fokker–Planck–Kolmogorov equations. This book discusses wide fractional generalizations of this fundamental triple relationship, where the driving process represents a time-changed stochastic process; the Fokker–Planck–Kolmogorov equation involves time-fractional order derivatives and spatial pseudo-differential operators; and the associated stochastic differential equation describes the stochastic behavior of the solution process. It contains recent results obtained in this direction.This book is important since the latest developments in the field, including the role of driving processes and their scaling limits, the forms of corresponding stochastic differential equations, and associated FPK equations, are systematically presented. Examples and important applications to various scientific, engineering, and economics problems make the book attractive for all interested researchers, educators, and graduate students. -->Contents: IntroductionThe Original Triangle: Brownian Motion, Itô Stochastic Calculus, and Fokker–Planck–Kolmogorov EquationFractional CalculusPseudo–Differential Operators Associated with Lévy ProcessesStochastic Processes and Time-ChangesStochastic Calculus for Time-Changed Semimartingales and Its Applications to SDEsFractional Fokker–Planck–Kolmogorov Equations --> -->Readership: Graduate students and researchers in science, engineering, economics. -->Keywords:Fractional Fokker–Planck Equations;Stochastic Differential Equations Driven by Time-changed Processes;Levy Processes;Fractional Brownian Motion;Inverse Stable Subordinators;Continuous Time Random Walk Approximations of Time-changed Processes;Pseudo-Differential Operators with Singular Symbols;Fractional Differential EquationsReview:Key Features:The novel theory of fractional Fokker–Planck–Kolmogorov equations and their connection with the associated stochastic differential equations driven by time-changed stochastic processes are discussed in detailThe book is rich in new ideas and applications to various real world problems arising in natural science, engineering, and economics.
